Three images from the pontifical Mass celebrated (probably) by Adam Cardinal Sapieha during Marian Congress in 1931 in Krakow. I personally admire this photos because of the Mariacki church that I particularly like most and would love to see back of Pontifical Mass there.
This must by Cardinal Sapieha celebrating, because of three reasons:
1. 7 candles on the altar
2. Use of pontifical cathedra (seat)
3. Use of archbishop cross
